Stop Input And Reset Input - IDEC MICROSmart FC6A Series User Manual

Stop Input and Reset Input

As described on "Start/Stop Operation" on page 4-18, the FC6A Series MICROSmart can be started and stopped using a stop input
or reset input, which can be designated from the Function Area Settings menu. When the designated stop or reset input is
turned on, the FC6A Series MICROSmart stops operation.
Since these settings relate to the user program, the user program must be downloaded to the FC6A Series MICROSmart after
changing any of these settings.
Stop Input
This section describes the stop input that stops execution of the FC6A Series MICROSmart user program with an external input.
Function Description
This function stops execution of the FC6A Series MICROSmart user program with an external input, such as a switch on a control panel.
Specify an FC6A Series MICROSmart normal external input for the stop input.
When the stop input is turned on, the user program that is being executed will stop. When the stop input is turned off, the user
program will be executed from the beginning.
RUN/STOP status
(When RUN/STOP control setting disabled)
*1 Even when M8000 (start control) is turned off, if the stop input is off, the FC6A Series MICROSmart maintains the RUN status.
*2 Even when the stop input is off, M8000 (start control) is off, so the FC6A Series MICROSmart does not change to the RUN status.
*3 When the function switch is set to the function to control FC6A Series MICROSmart RUN/STOP, the status changes to that corresponding to the
stop input and M8000 when the function switch is 1.
*4 When the function switch is set to the function to control FC6A Series MICROSmart RUN/STOP, the status will not change to the RUN status if
M8000 is turned on when the function switch is 0.
The external inputs that can be specified as the stop input are as follows.

Notes:
The stop input operation has priority over the WindLDR RUN/STOP operation (M8000 ON/OFF).

In addition to the FC6A Series MICROSmart stopping the user program with an external input, RUN/STOP operations can also be performed

by operating the function switch and by changing the start control (M8000) value with WindLDR.
While the reset input is on, user program execution stops. For details on the reset input, see "Reset Input" on page 5-5.

Reset Input
This section describes the reset input that clears FC6A Series MICROSmart device values with an external input.
Function Description
This function clears FC6A Series MICROSmart device values with an external input, such as a switch on a control panel. Specify an
FC6A Series MICROSmart normal external input for the reset input.
When the reset input is turned on, the user program that is being executed will stop, and all devices and general errors will be
cleared except the special internal relays and special data registers. When the reset input is turned off, the user program will be
executed from the beginning.
To turn off the reset input and execute the user program again, the following conditions must be met.
M8000 is on

The stop input is off (when the stop input has been configured)

The function switch is 1 (when the function to control FC6A Series MICROSmart RUN/STOP has been configured)

If these conditions are not met, the user program will not be executed and the FC6A Series MICROSmart will remain stopped even
if the reset input is turned off.
The external inputs that can be specified as the reset input are as follows.
